Answer:

d=9.2

Step-by-step explanation:

Distance Formula: d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Simply plug in your 2 coordinates into the distance formula to find distance <em>d</em>:

d=\sqrt{(1-8)^2+(1-(-5))^2}

d=\sqrt{(-7)^2+(1+5)^2}

d=\sqrt{49+(6)^2}

d=\sqrt{49+36}

d=\sqrt{85}

d=9.21954

d=9.2

ANSWER IF YOU LOVE YOUR LORD!!!! Which graph represents the solution to: 2k+8&lt;5k-1?
Leviafan [203]

Answer:

Third graph

Step-by-step explanation:

First, find the solution to the equation of inequality given.

2k + 8 < 5k - 1

Subtract 5k from both sides

2k + 8 - 5k < 5k - 1 - 5k

-3k + 8 < -1

Subtract 8 from both sides

-3k + 8 - 8 < -1 - 8

-3k < -9

Divide both sides by -3. (Note: < will change to > when dividing both sides with negative number)

\frac{-3k}{-3} > \frac{-9}{-3}

k > 3

The graph that will represent this solution will show that all values of k are greater than 3. 3 is not included as a solution. The "o" on top of the 3 on the number line won't be shaded to indicate that 3 is not included. And also, the arrow will point from 3 towards our right.

Therefore, the 3rd graph is the answer.

Help!! For this question I got 254.34 as my final answer but when I checked my answer it told me I was wrong?
Ugo [173]

Answer:

a = 254.5 mm² ( if using accurate value of π)

a = 254.4 mm² (if using 3.14 as approximate value of π)

Step-by-step explanation:

a = πr²

a = π * 9²

a = π * 81

(note using π = 3.1415926536)

a = 254.4690049408

Rounded

a = 254.5 mm²

(a = 254.4 If using π = 3.14)

He see a circle, so you need to find the area.
A = π * r²
A = π * 12²
A =  3.14 * 144 =

A = 452.16 miles²
